Which dozer classification includes models D-3 to D-5?

The classification of dozers is organized based on their operating weight and overall capability. In this context, the models D-3 to D-5 are categorized as "Light" dozers.

Light dozers, such as the D-3 and D-5, are designed for less demanding tasks compared to medium and heavy dozers, often used in residential, landscaping, and smaller commercial projects. They are typically more maneuverable and versatile, making them suitable for jobs where space is limited or less intense earthmoving is required.

Understanding these classifications is crucial for selecting the right equipment for specific projects, as it impacts not just performance but also operational efficiency and cost-effectiveness in job execution. The other classifications like heavy or medium would include larger, more powerful models that can handle tougher jobs, typically weighing significantly more than the light dozers. Therefore, D-3 to D-5 models fall within the light category due to their intended use and relative size within the range of dozers.
